Inventor: SUZUKI HIROSHI
IPC: H04L12/70
Filed: 1994-05-26
Abstract: In a packet-switched network in which a source station dissembles a packet into multiple cells and transmits them in sequence to a destination station, each switching system pre-assigns a unique set of VCI to each outgoing line. Corresponding respectively to incoming lines, each switching system includes line interface units for receiving normal signaling cells, a fast signaling cell and a data cell. Each interface unit includes a memory for storing the VCIs pre-assigned to the outgoing lines and a header translation table for defining relationships between a set of incoming VCIs and a corresponding set of outgoing VCIs. The interface unit assigns one of the stored VCIs to the fast signaling cell according to its destination, establishes a connection in the translation table between an incoming VCI and the assigned outgoing VC, and assigns an outgoing VCI of the established connection to the data cell according to an incoming VCI contained in the data cell. A central controller is provided for assembling the normal signaling cells into a signaling packet and assigning one of the stored VCIs to each of the normal signaling cells comprising the signaling packet. A self-routing switch provides routing of any of the cells according to a VCI assigned thereto.

Title: Biodegradable compositions produced by reactive blending of synthetic and naturally occurring polymers
Inventor: VAIDYA UTPAL R
IPC: C08H1/00
Filed: 1993-03-23
Abstract: A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a carbohydrate or protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer.

Patent CA-2133949-A1 (CA)
Title: Counterflow drum mixer for making asphaltic concrete and methods of operation
Inventor: BRASHEARS DAVID F
IPC: E01C19/10
Filed: 1994-10-20
Abstract: An inclined counterflow rotating drum mixer has a burner head intermediate an aggregate inlet at one end of the drum and an asphaltic concrete discharge at the opposite end of the drum. A fan supplies secondary air to the burner through a motive tube having an opening in communication with a mixing chamber between the burner head and the discharge end of the drum to aspirate gases from the mixing chamber for flow through the burner flame. The aspiration creates a negative pressure in the mixing chamber, causing a reverse flow of a portion of the combustion gases from the dryer chamber into the mixing chamber for preheating RAP input to the mixing chamber. RAP is also preheated by providing a preheat chamber adjacent the flame zone but segregated from direct contact with the flame to preheat the RAP. Hot and dried virgin aggregate is mixed with the RAP in the preheat chamber and valves are provided to prevent gases evolved from the RAP in the preheat chamber from flowing into the drying chamber.

Title: Pulley and bearing assembly for internal combustion engine front end accessory drive
Inventor: TOTH GERARD S
IPC: F16H7/08
Filed: 1994-11-01
Abstract: An idler pulley and bearing assembly for handling the drive belt of a front end accessory drive system of an internal combustion engine includes a bearing having an outer race and an inner race with an aperture for extending therethrough, and a mounting structure for securing the outer race of the bearing such that the outer race will not rotate.  A pulley mounted upon a shaft extending through the aperture in the inner bearing is attached to the inner race such that the shaft pulley and inner race rotate at the same speed.  This construction greatly reduces the rotational speed of the anti-friction elements within the bearing and preserves the bearing's lubrication, so as to prolong the life of the bearing, while reducing noise generated by the bearing.

Title: Wheel traction control for automotive vehicle
Inventor: SINGLETON WILLIAM A
IPC: B60K28/16
Filed: 1993-08-24
Abstract: A wheel traction control system establishes a velocity reference as a function of the wheel speeds of the non-driven wheels (36a, 36d) of the vehicle. When the wheel speed of either of the driven wheels (36b, 36c) exceeds the velocity reference, braking pressure is applied to the faster rotating wheel. The braking pressure is calculated as a function of the error or difference between the speed of the spinning wheel (36b or 36c) and the velocity reference, and as a function of wheel acceleration and the previously calculated braking pressure. Accordingly, smooth control of the spinning wheel (36b or 36c) is effected.

Patent CA-2151079-A1 (CA)
Inventor: SHINOHARA TOSHIAKI
IPC: H04N19/59
Filed: 1995-06-06
Abstract: A differential/absolute value image is derived by calculating an absolute value of each pixel in an image produced by subtracting a background image from an input image.  A mean value and a variance of a pixel in the differential/absolute value image are calculated from the levels of pixels included in a small region on the differential/absolute value image which has the pixel located at the center thereof.  The calculated mean value and variance of the pixel are used to distinguish whether the pixel is a pixel included in a moving object existing region, a background region, or an input image sudden change region.  A method of updating the background image is changed in accordance with whether the pixel is a pixel included in the moving object existing region, the background region, or the input image sudden change region.
